One story I heard was that there was a disagreement between Pizzolla on the one hand and Hambleton and Schmidt on the other hand about the use of TPR.
Pizzolla argued that adding the early and late ratings together just gave you an overall speed rating, and that using the two separately gave you more information. The other two said that the TPR was a compound rating that was more powerful than a simple speed rating.
Pizzolla went on to write "Handicapping Magic", which comes up with two separate ratings, one is speed adjusted for early pace, the other rates the final fraction adjusted for beaten lengths. Both use the fractions of the fulcrum horse as kind of projection or par, rating each horse relative to the fulcrum. The two ratings are in entirely different formats, and cannot be combined.
